Description

Technical Field

[0001] This utility model belongs to the field of welding processing technology, and in particular relates to a welding wire conveying fixture. Background Technology

[0002] Currently, welding robots are typically programmed to perform automated welding operations according to specified actions. During the welding process, it is generally necessary to install appropriate welding wire feeding fixtures on the welding robot to ensure that the welding wire can be continuously fed to the processing end of the welding robot.

[0003] In the existing technology, most wire feeding fixtures used for welding robots have the following technical problems: during the wire feeding process, the wire may be subjected to excessive local stress and bend, resulting in abnormal stiffness when the wire is fed to the processing end of the welding robot. This can easily cause serpentine welds, inconsistent weld dimensions, and a large amount of abnormal spatter, thus affecting the welding quality. Utility Model Content

[0004] The purpose of this utility model is to provide a welding wire feeding device to address the aforementioned technical problems.

[0005] In view of this, the present invention provides a welding wire feeding fixture, comprising:

[0006] The base frame has storage slots inside.

[0007] The conveying assembly includes a first roller and a second roller, both of which are rotatably disposed within the storage slot;

[0008] A drive assembly, mounted on the base frame, is used to drive the first roller to rotate;

[0009] The welding wire to be fed passes between the first roller and the second roller, which are used to clamp the welding wire radially.

[0010] Furthermore, the driving component includes:

[0011] The main gear is rotatably mounted in the storage slot;

[0012] The drive unit is mounted on the base frame and is used to drive the main gear to rotate;

[0013] The conveying assembly also includes a secondary gear, which is rotatably disposed in the storage slot and connected to the first roller, with the main gear and the secondary gear meshing with each other.

[0014] Furthermore, the conveying components are in two sets and are arranged along the direction of the welding wire.

[0015] Furthermore, it also includes a protective cover, which is installed on the base frame by fasteners to cover the storage compartment.

[0016] Furthermore, the protective cover is made of transparent material.

[0017] The beneficial effects of this utility model are:

[0018] This welding wire feeding fixture utilizes the transmission between a main gear and a secondary gear. A drive motor controls the rotation of the main gear, which in turn drives the first roller connected to the secondary gear. The rotation of the first and second rollers clamps and feeds the welding wire, allowing it to automatically travel to the processing end of the welding robot, thus completing the automated welding wire feeding operation. Simultaneously, the use of the first and second rollers to clamp and guide the welding wire minimizes the clamping force during transport, reducing bending and deformation caused by excessive local pressure. This prevents serpentine weld bends, inconsistent weld dimensions, and excessive abnormal spatter, effectively improving welding quality and demonstrating high practicality.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] Example 1:

[0024] This embodiment provides a welding wire feeding fixture, including:

[0025] Base frame 1, with a storage slot 2 inside the base frame 1;

[0026] The conveying assembly includes a first roller 3 and a second roller 4, both of which are rotatably disposed in the storage slot 2.

[0027] A drive assembly, mounted on the base frame 1, is used to drive the first roller 3 to rotate;

[0028] The welding wire 7 to be fed passes between the first roller 3 and the second roller 4, and the first roller 3 and the second roller 4 are used to clamp the welding wire 7 radially.

[0029] In this technical solution, the bottom of the base frame 1 is mounted on the welding robot using fasteners. An inlet and an outlet are respectively located on both sides of the base frame 1, and these inlets and outlets are connected to the storage slot 2 of the base frame 1. A rotatable first roller 3 and a second roller 4 are installed within the storage slot 2. Both the first roller 3 and the second roller 4 are rotatably connected to the base frame 1 via bearings, and are positioned opposite each other. A gap exists between the first roller 3 and the second roller 4 to allow the welding wire 7 to pass through.

[0030] The welding wire 7 enters the storage tank 2 through the feed inlet, then passes through the gap between the first roller 3 and the second roller 4, and finally exits through the discharge outlet, completing the wiring arrangement of the welding wire 7. Then, the first roller 3 is rotated by the drive assembly. Since both the first roller 3 and the second roller 4 are pressed against the welding wire 7, when the first roller 3 rotates, it will move the welding wire 7 in conjunction with the second roller 4, causing the welding wire 7 to be clamped forward along the wiring direction, thereby realizing the feeding of the welding wire 7 to the welding processing end of the welding robot.

[0031] Furthermore, the drive assembly includes a main gear 5 and a drive component. The main gear 5 is rotatably disposed within the storage slot 2, and the drive component is mounted on the base frame 1 to drive the main gear 5 to rotate. The drive component can be a drive motor. The conveying assembly also includes a secondary gear 6, which is rotatably disposed within the storage slot 2 and connected to the first roller 3. The main gear 5 and the secondary gear 6 mesh with each other. Through structural design, the drive motor controls the rotation of the main gear 5, which in turn drives the first roller 3 to rotate synchronously, thus enabling the first roller 3 and the second roller 4 to rotate and clamp the welding wire 7.

[0032] In summary, this welding wire 7 conveying fixture utilizes the transmission between the main gear 5 and the auxiliary gear 6. A drive motor controls the rotation of the main gear 5, which in turn drives the first roller 3 connected to the auxiliary gear 6. The rotation of the first roller 3 and the second roller 4 clamps and feeds the welding wire 7, allowing it to automatically travel to the processing end of the welding robot, thus completing the automated welding wire 7 conveying operation. Simultaneously, the clamping force on the welding wire 7 by the first roller 3 and the second roller 4 minimizes the clamping force during conveying, reducing bending and deformation caused by excessive local pressure. This avoids serpentine weld bends, inconsistent weld dimensions, and excessive abnormal spatter, effectively improving welding quality and demonstrating high practicality.

[0033] Example 2:

[0034] This embodiment provides a welding wire feeding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] Furthermore, the conveying components are in two sets and are arranged along the routing direction of the welding wire 7.

[0036] In this technical solution, the conveying assembly is configured into two sets, each set including a first roller 3 and a second roller 4 for clamping the welding wire 7, and a secondary gear 6. The two secondary gears 6 are located on both sides of the main gear 5 and mesh with it. When the spur gear rotates, it drives the two secondary gears 6 to rotate synchronously and in the same direction, thus enabling the first roller 3 and the second roller 4 of each set of conveying assemblies to simultaneously clamp the welding wire 7. This structural design, utilizing two sets of conveying drum assemblies, increases the frictional traction force applied to the welding wire 7, thereby effectively enhancing the stability of the welding conveying process.

[0037] Example 3:

[0038] This embodiment provides a welding wire feeding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] Furthermore, a protective cover is included, which is fastened to the base frame 1 to seal the storage slot 2. By sealing the storage slot 2 with the protective cover, external objects can be prevented from bumping into components such as the main gear 5, secondary gear 6, and welding wire 7 inside the storage slot 2, thus preventing damage to the components of the welding wire 7 conveying fixture and effectively preventing disruption to the welding wire 7 conveying operation. Furthermore, the protective cover is made of transparent material. This structural design ensures protection while allowing workers to observe the internal structure of the welding wire 7 conveying fixture and understand the conveying status of the welding wire 7, making it highly practical.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
